The Australian experience suggests China was much better off copying H-60 rather than NH90.I wonder, could it have been possible to make the Z-20 based on the NH90 instead, it's a much more modern helicopter and AVIC has gotten license transfers from Airbus before such as the H175. Would also have prevented the insufferable american whining about the Z-20 being a black hawk copy
Got me more curious so I went to look and found this on the wiki.Spare parts of lack there of. Faster blade erosion, doors to narrow to support infantry as they unload. High operating cost.
